Fungus Gnat Control
DAMAGE
Sudden wilting, poor growth, chlorosis (yellowing), and foliage loss. Larval feeding can cause significant root damage and severely inhibit nutrient uptake.
CONTROL
• Monitor & Trap: Use yellow sticky traps to kill reproducing adults. Gridded traps to monitor infestation level and effectiveness of controls. • Cultural Controls: Avoid overwatering and correct drainage issues. • Biological Controls: Sf Beneficial Nematodes for larval control,
S. scimitus for larvae and pupae. • Insecticides: Bti (Bacillus thuringiensis israelensis) can be used in conjunction with biological control for increased control. Drench with SNS 203 Soil Drench/Foliar Spray (pg. 31) for infestations of multiple soil pests.
Fungus Gnat Predator - Stratiolaelaps
scimitus (=Hypoaspis miles)
Stop Destructive Fungus Gnats & Thrips In Their Developing Soil Stages.
TARGET: Fungus gnats, western flower thrips, springtails, mold mites, spider mites, cactus root mealybugs, strawberry root weevils and black vine root weevils.
Stratiolaelaps scimitus (=Hypoaspis miles)
DESCRIPTION: This tiny brown mite naturally inhabits the top layer of soil where larvae and pupae dwell. Female predatory mites lay their eggs in soil and the nymphs and adults feed on pests. SUGGESTED USE (Depending upon level of infestation): ≈5,000-10,000 mites treat approximately 1,000 sq. ft. Release ≈25,000-50,000/acre depending on level of infestation. Apply weekly until infestation subsides. Weekly release programs available. Please Call. Trap adult infestations using Blue Sticky Traps. Reinforce with applications of beneficial nematodes. Temperature: Moderate 60-74ºF Soil Conditions: Moist soil. Not too damp. 1154000 ≈12,500 Count $19.00 1154002 ≈25,000 Count $30.00 1154005 ≈50,000 (2 x 25,000) $50.00 1154010 ≈125,000 in 5 Liter Bag $130.00

Rove Beetle - Dalotia coriaria (=Atheta coriaria)
For Indoor Control Of Soil Dwelling Pests!
TARGET: Fungus gnats (sciarid flies), thrips and shore flies.
DESCRIPTION: Rove beetles will feed on small soil-dwelling pest larvae and eggs. Adults are a brown-black color, 3-4 mm long and winged. They are predacious in all stages and develop from egg to adult in about 21 days; passing through three larval instars prior to pupation and adulthood. Adults consume about 150 pest fungus gnat eggs per day. Compatible with Stratiolaelaps scimitus (=Hypoaspis miles). Winged adults have high dispersal and colonization rates and are not recommended for outdoor use.
Dalotia coriaria (=Atheta coriaria)
SUGGESTED USE (Depending upon level of infestation): Use season-long, in covered crops such as ornamentals, cucumbers, strawberries and mushrooms. Apply directly to growing medium surface. Apply approx. 1-5 predators per sq. ft. For high infestation, increase application rate and consider pairing with another suitable predator or parasite like S. scimitus, beneficial nematodes, or specific mite predators. Temperature: Moderate 55-80ºF Relative Humidity: 50-80% 1101330 ≈500 Adults $54.00 1101331 ≈1,000 Adults $78.00 1101332 ≈3,000 Adults $170.00 1101334 ≈5,000 Adults $250.00

Monitor & Identify Using Sticky Traps
Trapping is the most efficient way to monitor your crop for pest insects and can often indicate the insect’s presence early enough that other control measures can be taken. Bright yellow traps attract whiteflies and aphids while blue traps can draw thrips and leafminers.
